Jackass alum Johnny Knoxville is no stranger to crazy stunts and antics, and he probably has a few more in his future with a newborn on his hands! Knoxville (whose real name is Phillip John Clapp) and his wife Naomi Nelson welcomed a daughter on October 6th. Arlo joins big brother RockoAkira (20 months) and sister Madison (15 years, with Knoxville’s ex-wife Melanie) in the Knoxville household.

Johnny Knoxville, star of the various Jackass films and shows, is anticipating the arrival of his third child with his wife, Naomi. Baby #3, who is due this fall, will join big brother Rocko (16 months) and big sister Madison (15 years, from Knoxville’s previous marriage) in the stuntman’s home.

Apparently, the Jackass star needed a little time — about 13 years — to recuperate from his last bout. Knoxville has a thirteen-year-old daughter, Madison, from a previous marriage. On Sunday, however, he and girlfriend Naomi Nelson officially took the plunge when they welcomed Rocko Akira Clapp. Little Rocko weighed 8 pounds and was 20 inches long.

Johnny Knoxville, best known for his daredevil stunts on the hit show Jackass, is going to be a father again! The actor confirmed on his blog that he and girlfriend Naomi Nelson are expecting a baby together. Knoxville wrote “we are excited as all hell, and can’t wait ’til the little booger gets here.” His thirteen year-old daughter Madison, excited about her role as big sis, is helping to pick out baby items for her new little brother or sister. The newest little Knoxville is due in late winter.
